What is the maximum span on a double 2x12 beam supporting 2x8 ceiling rafters and an acoustical ceiling?
Depends on the area above the ceiling joists. Is it a live load (living space) or dead load (just the joists with maybe an attic above)? Also, the length of the ceiling joists from the last bearing point is a factor. How much weight is bearing on the beam is the critical issue.
